(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_MALLOC

A macro to tag a function as an allocator.

Header File

Defined in <SDL3/SDL_begin_code.h>

Syntax

#define SDL_MALLOC __declspec(allocator) __desclspec(restrict)

Remarks

This is a hint to the compiler that a function is an allocator, like malloc(), with certain rules. A description of how GCC treats this hint is here:

https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-malloc-function-attribute

On compilers without allocator tag support, this is defined to nothing.

Most apps don't need to, and should not, use this directly.

Version

This macro is available since SDL 3.1.3.
